        "description": "Tool description",
        "method": "GET",
        "inputSchema": {
          "type": "object",
          "properties": {}
        }
      }
    }
  },
  "webhooks": {
    "serviceName": {
      "baseUrl": "${WEBHOOK_URL}",
      "tools": {
        "toolName": {
          "description": "Tool description",
